Huh? Am I Ok?

For the past few days, I had a strange sensation in my chest. Today I feel cold in the area around my left chest, near the heart. I wonder why - maybe it is the chain of events that have been moving so fast lately, that I have a hard time catching up.

Everyday I walked around 400 meters from the school gates to the bottom of the hill where my mother will pick me up. No problems, except that you have to walk 150 meters (in distance, not height) uphill, then walking down will be quite a breeze if not for the crazily driven vehicles that threaten to turn me into pancakes. There are dogs, but they are hardly a problem - they consider me as a friend.

I know I shouldn't complain about walking. Others have it harder than me. My mother used to walk two kilometers from the bus stop to her house up on a hill. And the journey from the school to the house took about two hours, so it's dark by the time she reached home. She left home early too, around 5 am.

My daily scheduele are as follows:
0545 - Wake up, do everything that you do every morning.
0620 - Breakfast.
0630 - Leave for school. If my sister woke up late, it will be 0640. Damn.
0640 - Arrival. 0650 if sister woke up late.
0710 - Class starts (offically)
0715/0720 - Class starts (unofficially)
1400 - Class ends (unofficially)
1410 - Class ends (officially)

And people in other schools went back at 1240. What the hell?
